In the process of photosynthesis, plants use carbon dioxide (CO2), water (H20), and light energy to produce a sugar (C6H2O) and oxygen (O2). In the process of aerobic respiration, animals and
plants release energy
from sugar and oxygen and produce carbon dioxide and water. The chemical
equations that describe these reactions look like this
6CO2 + 6H2O + light → CH,206 +602
CH,206 +602 → 6CO2 + 6H2O + energy
+
How do these equations explain why the total amount of O, and Co, remains the same?
